A questionnaire survey and comparative analysis was conducted among disaster-experienced local government officials and the General Advisers for Disaster Management (GADM) to clarify the characteristics of perceptions and behaviors of disaster management tasks. As a result of the survey, it was clarified that disaster-experienced local government officials have the higher tendency to think that each element of disaster management task is an action mainly taken by themselves, than support staffs. The characteristics of the disaster management process followed by disaster-management experts were extracted.
